這是101年的考題
Forks trace their origins back to the ancient Greeks. Forks at that time were
fairly large with two tines that aided in the carving of meat in the kitchen.
The tines prevented meat from twisting or moving during carving and allowed
food to slide off more easily than it would with a knife.
slide off more easily
讓食物更容易被切?
slide off 該如何理解
請指教
謝

slide off http://en.wiktionary.org/wiki/slide_off這片語的意象是讓一個斜面滑落，而後面也說了「跟刀子一起使用時slide off會比較容易」，可以用你理解的方式啊

古早以前只有刀沒有叉，洋人吃東西都是用刀切了，直接插下去送進嘴裡所以這裡會說拿叉子叉食物，跟刀子相比，比較容易弄下來
